Given numbers are 909,221,905,352,788

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 909,221,905,352,788 is 12607054368480.

Find LCM of 909,221,905,352,788 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 909 x 221 x 905 x 88 x 197 = 12607054368480

Therefore, the lowest common multiple of 909,221,905,352,788 is 12607054368480.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

909 x 221 x 905 x 352 x 788 = 50428217473920

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

909 : 1, 3, 9, 101, 303, 909

221 : 1, 13, 17, 221

905 : 1, 5, 181, 905

352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352

788 : 1, 2, 4, 197, 394, 788

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,221,905,352,788, is 1.

Now, the common factors can be found like this.

909:3x 3x 101

221:13x 17

905:5x 181

352:2x 2x 2x 2x 2x 11

788:2x 2x 197

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 50428217473920/(1x4)

LCM = 50428217473920/4

LCM = 12607054368480

Thus, we can understand that the LCM of 909,221,905,352,788 is 12607054368480.
